Definitions

  • the present invention relates to a work vehicle having an engine and a hydraulic pump driven by the engine for feeding work oil to a work implement connected to a traveling vehicle body.
  • the work implement is connected to the traveling vehicle body and the hydraulic pump is connected to e.g. an output shaft of the engine, so that the engine is used as a drive source for the hydraulic pump and the hydraulic pump feeds work oil to the work implement for carrying out a desired work.
  • the rotational speed of the engine a target rotational speed of the engine corresponding to an operation of an accelerator operation section is obtained and the engine rotational speed is controlled to this obtained target rotational speed.
  • the engine is used as the drive source for the hydraulic pump, merely with controlling the engine rotational speed to a target rotational speed corresponding to an operation of an accelerator operation section, sometimes, it is not possible to obtain a sufficiently high rotational speed for feeding the amount of work oil required for appropriate operation of the work implement, so that an appropriate operation of the work implement may not be possible.

  • a fuel increasing switch separately of the accelerator operation section, and when this fuel increasing switch is operated, the engine rotational speed is increased from the target rotational speed corresponding to an operation of an accelerator operation section, by an amount of a predetermined rotational speed.
  • US 2008/0319618 A1 discloses a work vehicle in which an optimized engine speed parameter is determined with regard to fuel consumption, reduced emissions and/or increased productivity.
  • EP 2 221 042 A1 discloses an engine control device for a working vehicle.
  • the engine is used not only as the drive source for causing the traveling vehicle body to travel, but also as the drive source for the hydraulic pump.
  • the engine rotational speed can be controlled to an appropriate rotational speed.
  • the arrangement simply controls the engine rotational speed to a set rotational speed. Therefore, the arrangement fails to take into account both the target rotational speed and the rotational speed of the hydraulic pump. Hence, it may happen that a sufficiently high rotational speed cannot be obtained as the rotational speed of the hydraulic pump eventually.
  • the present invention has been made in view of the above and its object is to provide a work vehicle capable of obtaining, as a rotational speed of the hydraulic pump, a high rotational speed as sufficient as possible for feeding work oil required for an operation of the work implement, without giving excessive load to the engine.

  • the engine rotational speed control section effects the high-speed-rotation control.
  • the target rotational speed is higher than the high-speed-rotation rotational speed
  • the engine rotational speed is controlled to this target rotational speed.
  • the high-speed-rotation rotational speed is higher than the target rotational speed
  • the engine rotational speed can be controlled to this high-speed-rotation rotational speed.
  • the engine rotational speed control section effects the accelerator control, so that the engine rotational speed can be controlled without further increasing the speed from the target rotational speed. With this, it becomes possible not to increase the engine rotational speed more than necessary, thus appropriately preventing application of excessive load to the engine.
  • the work vehicle further comprises a traveling speed changer device capable of speed changing operations in response to an operation of a speed changer section; and a restraint section for restraining execution of the high-speed-rotation control by the engine rotational speed control section in case the speed range of the speed changer device is switched to a high speed range.

  • the engine rotational speed control section increases the engine rotational speed with setting an increasing speed of the engine rotational speed slower than a set increasing speed.
  • the engine rotational speed control section When the engine rotational speed control section is to effect the high-speed-rotation control, if the increasing speed of increasing the engine rotational speed is high, this tends to invite increase in the emission amount of particulate matters (PM) exhausted from the engine. Then, in executing the high-speed-rotation control, by increasing the engine rotational speed with setting the increasing speed of the engine rotational speed slower than a set increasing speed, the emission amount of the particulate matters (PM) can be restrained to the minimal amount.
  • the work vehicle further comprises a vehicle speed hold device for holding the vehicle speed of the traveling vehicle body in case the engine rotational speed control section executes the high-speed-rotation control.
  • the work vehicle further comprises a hydraulic stepless speed changer device capable of speed change through variable adjustment of a swash plate angle, and the vehicle speed hold device holds the vehicle speed of the traveling vehicle body through control of the swash plate angle of the hydraulic stepless speed changer device.
  • the traveling hydraulic stepless speed changer device capable of speed change through variable adjustment of a swash plate angle
  • the holding of the vehicle speed of the traveling vehicle body can be appropriately effected through the simple arrangement of controlling the swash plate angle of the hydraulic stepless speed changer device.

  • the driver can operate the front loader by operating the operation lever. And, since a switch as the high-speed-rotation instruction operation section is provided at the grip portion of this operation lever, the driver can effect a switch operation such as a pressing operation while operating the operation lever. Therefore, the load on the driver can be lessened and at the same time a high-speed-rotation instruction can be given at an appropriate timing.

  • the speed position of the speed changer operation section 24 is detected by the unillustrated sensor and the detection information of this sensor is inputted to the main control section 35.
  • the main control section 35 can recognize based on the speed position of the speed changer operation section 24 which of the high speed range, the intermediate speed range and the low speed range the speed change of the gear speed changer device 7 is.
  • the main control section 35 includes a restraint section 47 for restraining execution of the high-speed-rotation control by the engine rotational speed control section 46 in case the speed change range of the gear type speed changer device 7 is switched to the high speed range.
  • a restraint section 47 for restraining execution of the high-speed-rotation control by the engine rotational speed control section 46 in case the speed change range of the gear type speed changer device 7 is switched to the high speed range.
  • the high-speed-rotation control will be executed after making sure that the speed range of the gear speed changer device 7 is switched to the high speed range.
  • the engine rotational speed is controlled to whichever higher one of the target rotational speed and the high-speed-rotation rotational speed, whereby a sufficiently high rotational speed can be obtained as a rotation speed of the hydraulic pump 20 for feeding work oil to the front loader 3.
  • the engine rotational speed control section 46 increases the engine rotational speed with setting an increasing speed of the engine rotational speed slower than a set increasing speed. Regarding the set increasing speed, this is set such that the emission amount of particulate matters (PM) exhausted from the diesel engine will not exceed a set permissible amount. With this, for example, in the high-speed-rotation control, the engine rotational speed control section 46 will increase the engine rotational speed by a set slow increasing speed which is set in advance to be slower than the set increasing speed, thereby to prevent the emission amount of the particulate matters (PM) from exceeding the set permissible amount.
  • a vehicle speed hold device 48 for holding the vehicle speed of the traveling vehicle body 2 when the engine rotational speed control section 46 effects the high-speed-rotation control.
  • This vehicle speed hold device 48 is comprised of a swash plate control section 42.
  • the vehicle speed hold device 48 effects a vehicle speed hold control for holding the vehicle speed of the traveling vehicle body 2 to the speed prior to the execution of the high-speed-rotation control, by controlling the swash plate angle of the hydrostatic stepless speed changer device 6 (step #4 in Fig. 5 ).
  • the horizontal axis represents the lapsed time and the vertical axis represents the engine rotational speed in the graph shown in the upper section, whereas the vertical axis represents the swash plate angle of the hydrostatic stepless speed changer device 6 in the graph shown in the middle section and the vertical axis represents the vehicle speed in the graph shown in the lower section, respectively.
  • the swash plate control section 42 monitors the vehicle speed of the traveling vehicle body 2 based on the detection information of the vehicle speed sensor 26.
  • the swash plate control section 42 controls the swash plate angle of the hydrostatic stepless speed changer device 6 such that when the engine rotational speed control section 46 effects the high-speed-rotation control, the vehicle speed of the traveling vehicle body 2 at the start timing T1 of this high-speed-rotation control may be maintained. That is, when the engine rotational speed control section 46 effects the high-speed-rotation control, the engine rotational speed is increased.
  • the swash plate control section 42 reduces the swash plate angle of the hydrostatic stepless speed changer device 6 so that the vehicle speed detected by the vehicle speed sensor 26 may be the vehicle speed at the start timing T1 of the high-speed-rotation control.
  • the swash plate control section 42 effects a vehicle speed hold control, as shown in the graph shown in the lower section in Fig 6 , the vehicle speed of the traveling vehicle body 2 is maintained and held at the vehicle speed of the traveling vehicle body 2 at the start timing T1 of the high-speed-rotation control.
